eStore Inventory going Negative?

[RobertRice]

Hello!

We sell physical items, and we had quantity 4 available of a given item. We of course set this field in eStore for teh item. Somehow, eStore allowed 7 people to purchase the item, so now the available quantity of the item is -3…
It looks like 4 people checked out within the same 5 minute span, but not at the EXACT same time. How can we prevent this from happening in the future?

The shortcodes we use are only:
[wp_eStore_category_products_fancy id=4 style=1 order=1]
[wp_eStore_cart_fancy1]

We are on WP eStore v8.5.0

Hi, Our plugin cannot handle that particular scenario that you described. The plugin updates the inventory after the payment has been made. So if there are a lot of users trying to purchase the same item at the same time and you have a limited quantity, it can face the issue that you explained. When they add the item to the cart and keep it in the cart while someone else is paying for it at the same time, someone can miss out.

I have sent you an email for it.
